The following sections describe how to configure Radio Settings on the Professional Access Point:

•Understanding Radio Settings

•Navigating to Radio Settings

•Configuring Radio Settings

•Updating Settings

Understanding Radio Settings

Radio settings directly control the behaviour of the radio device in the access point and its interaction with the physical medium, that is, how and what type of electromagnetic waves the access point emits. You can specify whether the radio is on or off, radio frequency (RF) broadcast channel, beacon interval (amount of time between access point beacon transmissions), transmit power, IEEE 802.11 mode in which the radio operates, and so on.

The Professional Access Point can broadcast in the following modes:

•IEEE 802.11b

•IEEE 802.11g

The IEEE mode along with other radio settings are configured as described in “Navigating to Radio Settings” on page 130 and “Configuring Radio Settings” on page 130.
